Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is for reference. Figures 1-8 The water tank assembly 100 according to the embodiments of the present utility model can ensure the sealing between the various structures, thereby ensuring the operational reliability of the water tank assembly 100, improving the washing effect, and thus improving the user experience.

[0041] like Figures 1-8 As shown, a water tank assembly 100 according to an embodiment of the present invention includes: a water tank shell 1, a heat exchange component 2, and a fixing component 3.

[0042] The water tank shell 1 has a water storage cavity 17 and a heat exchange cavity 14. The heat exchange component 2 is located in the heat exchange cavity 14. The heat exchange component 2 has a heat exchange channel 21 for exchanging heat with the heat exchange cavity 14. The end of the heat exchange channel 21 is connected to the water storage cavity 17. The end of the heat exchange component 2 is fixed to the water tank shell 1 by a fixing assembly 3. The fixing assembly 3 includes a fixed bracket 4 and a sealing member 5 connected to each other. The fixed bracket 4 is fixed to the water tank shell 1. The sealing member 5 seals and presses against the outer peripheral wall of the heat exchange component 2 and the inner wall of the water tank shell 1 respectively, so that the water storage cavity 17 and the heat exchange cavity 14 are not connected.

[0043] Among them, washing equipment can be set up as dishwashers, which are devices that automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Dishwashers can be set up as cabinet-style, countertop-style, or sink-integrated models to meet the needs of different usage scenarios. Dishwashers can integrate washing, disinfection, and drying functions, which can reduce labor intensity, improve cleanliness and hygiene, and improve work efficiency due to their short cleaning time. They can be used and washed immediately, thereby improving ease of use and user experience.

[0044] Specifically, the water tank assembly 100 is provided with a water tank shell 1, which is located on the outermost side of the water tank assembly 100 and can provide overall support for the water tank assembly 100. The interior of the water tank assembly 100 is set as a cavity, which can provide mounting points for the internal structure of the water tank assembly 100 and ensure the operational reliability of the water tank assembly 100. A water storage cavity 17 and a heat exchange cavity 14 are formed inside the water tank assembly 100. The water storage cavity 17 can be used to store a first medium, and a second medium can circulate in the heat exchange cavity 14. The first medium can exchange heat with the first medium through the heat exchange cavity 14. When the temperature of the second medium is higher than that of the first medium, the heat can be transferred to the first medium and then stored in the water storage cavity 17.

[0045] Furthermore, the water tank assembly 100 is equipped with a heat exchanger 2, which can be configured as a heat exchange tube, etc. In actual installation, the heat exchange tube can be constructed as a microchannel tube, and can be configured as a flat tube or a round tube, etc., with high flexibility in configuration. This allows a heat exchange channel 21 to be formed inside the heat exchanger 2, and the end of the heat exchange channel 21 is connected to the water storage chamber 17. That is, both ends of the heat exchange channel 21 are connected to the water storage chamber 17, so that the first medium in the water storage chamber 17 can flow into the heat exchange channel 21, and then flow back into the water storage chamber 17 through the heat exchange channel 21. The heat exchanger 2 is set in the heat exchange chamber 14, and the second medium can flow in the heat exchange chamber 14, so that the first medium can exchange heat with the second medium through the heat exchanger 2. After heat exchange, the first medium can flow back into the water storage chamber 17 to store the heat in the water storage chamber 17.

[0046] Furthermore, the end of the heat exchanger 2 is fixed to the water tank shell 1 by the fixing assembly 3, which can improve the fixing stability and reliability of the heat exchanger 2 in the water tank shell 1. The fixing assembly 3 is provided with a fixing bracket 4 and a sealing element 5. The fixing bracket 4 can be fixedly connected to the water tank shell 1 by welding, snap-fitting or bonding. The sealing element 5 and the fixing bracket 4 can be connected by plugging or coating. The sealing element 5 seals and presses against the outer peripheral wall of the heat exchanger 2 and the inner wall of the water tank shell 1 respectively, and prevents the water storage cavity 17 from communicating with the heat exchange cavity 14. That is, the sealing element 5 can achieve the sealing between the heat exchanger 2 and the fixing bracket 4, and also the sealing between the fixing bracket 4 and the water tank shell 1, preventing the second medium in the heat exchange cavity 14 from overflowing through the gap between the heat exchanger 2 and the fixing bracket 4 or through the gap between the fixing bracket 4 and the water tank shell 1, thereby improving the sealing performance between the water storage cavity 17 and the heat exchange cavity 14.

[0047] Furthermore, the sealing element 5 can also be used to separate the water storage chamber 17 and the heat exchange chamber 14, thereby simplifying the structure of the water tank assembly 100, reducing the processing difficulty of the water tank assembly 100, reducing the cost of the water tank assembly 100, and also reducing the space occupied by the water tank assembly 100, which facilitates the miniaturization and compact design of the water tank assembly 100.

[0048] It is understood that the water storage chamber 17 and the heat exchange chamber 14 are sealed at intervals by the sealing element 5, which can prevent the mixing of the first medium and the second medium. For example, in the embodiment where the water tank assembly 100 is used in a dishwasher, the seal between the first medium and the second medium can prevent the mixing of the high-temperature washing medium containing impurities and the clean low-temperature washing medium, so as to avoid contamination of the clean washing medium in the water tank assembly 100, ensure the washing effect of the dishwasher, and prevent the generation of odors in the water tank assembly 100 of the dishwasher, thereby improving the cleaning effect and user experience of the dishwasher. In industrial application scenarios where the first medium and the second medium are respectively low-temperature refrigerant and high-temperature refrigerant, the mixing of low-temperature refrigerant and high-temperature refrigerant can be avoided, which can improve the stability and safety of industrial equipment using the water tank assembly 100 of this application embodiment and reduce safety hazards.

[0049] It should be noted that in some embodiments, the first medium or the second medium can be the same medium, while in other embodiments, the first medium and the second medium can be different media. The first medium and the second medium can be water, refrigerant, etc., and in some cleaning application scenarios, they can also be washing media.

[0050] According to the water tank assembly 100 of this utility model embodiment, the sealing member 5 is sealed and pressed against the outer peripheral wall of the heat exchange member 2 and the inner wall of the water tank shell 1, which can improve the sealing performance between the heat exchange chamber 14 and the water storage chamber 17, and improve the fixation stability and reliability of the heat exchange member 2 in the water tank shell 1. The sealing member 5 is also used to divide the heat exchange chamber 14 and the water storage chamber 17, so that the sealing member 5 is constructed as a reusable structure, which can simplify the structure inside the water tank shell 1, improve the compactness of the internal structure of the water tank shell 1, realize the miniaturization and compact design of the water tank assembly 100, and reduce the installation cost of the water tank assembly 100. At the same time, it can prevent the heat exchange chamber 14 and the water storage chamber 17 from communicating, improve the working stability and reliability, and ensure the washing effect, improve the user experience, and have a better performance and wider applicability.

[0051] In some embodiments, the fixed bracket 4 has an insertion space 44, and the sealing member 5 is inserted into the fixed bracket 4.

[0052] Specifically, the fixing component 3 is provided with a fixing bracket 4 and a sealing element 5, and as follows: Figures 2-3As shown, the fixed bracket 4 is provided with an insertion space 44. One side of the insertion space 44 is open, so that the sealing element 5 can be partially placed in the insertion space 44, thereby allowing the sealing element 5 to be inserted and mated with the fixed bracket 4. The installation is convenient. The sealing element 5 can be made of rubber or other materials, so that the hardness of the sealing element 5 is low. When the sealing element 5 is inserted into the insertion space 44 of the fixed bracket 4, the fixed bracket 4 can support the sealing element 5 and limit the degree of deformation of the sealing element 5, so as to avoid excessive stress on the sealing element 5 and excessive deformation, thus ensuring the sealing performance of the sealing element 5.

[0053] In addition, the seal 5 and the fixed bracket 4 are inserted and matched, so that the fixed bracket 4 can restrict the displacement of the seal 5 in other directions except the insertion direction, and the fixed bracket 4 can be fixedly connected to the water tank shell 1, thereby ensuring the reliability of the installation position of the seal 5 in the water tank shell 1, so as to ensure the sealing effect of the seal 5 between the water storage chamber 17 and the heat exchange chamber 14, and ensure the operational reliability of the water tank assembly 100.

[0054] In some embodiments, the sealing element 5 is integrally coated onto the fixed bracket 4, that is, the sealing element 5 can be constructed as a coated structure. The fixed bracket 4 and the heat exchanger 2 can be placed in the same mold, and liquid coating is injected into the mold, which can then achieve fixation and sealing between the heat exchanger 2 and the fixed bracket 4, and can achieve sealing to prevent soft glue from overflowing during the secondary coating process. After the secondary coating is completed, the fixed component 3 and the heat exchanger 2 can be further assembled into the heat exchange chamber 14, and at this time the outer periphery (i.e., the side, bottom and top surfaces) of the sealing element 5 can be elastically deformed and sealed by extrusion pressure, which can improve the impact resistance of the sealing element 5, improve manufacturing efficiency, and ensure reliability in use.

[0055] In some embodiments, the fixing bracket 4 includes a first sub-plate 41 and a second sub-plate 42, the first sub-plate 41 and the second sub-plate 42 are connected by a connecting plate 43, and the first sub-plate 41 and the second sub-plate 42 are spaced apart to define an insertion space 44, and at least a portion of the sealing member 5 is inserted between the first sub-plate 41 and the second sub-plate 42.

[0056] Specifically, such as Figures 2-3 As shown, the fixed bracket 4 is provided with a first sub-plate 41 and a second sub-plate 42. The first sub-plate 41 and the second sub-plate 42 can be set as identical plate structures. The first sub-plate 41 and the second sub-plate 42 are spaced apart, and a connecting plate 43 is provided between the first sub-plate 41 and the second sub-plate 42. That is, one side of the connecting plate 43 can be connected to the first sub-plate 41 by welding or integral molding, and the other side of the connecting plate 43 can be connected to the second sub-plate 42 by welding or integral molding, so that the connecting plate 43, together with the first sub-plate 41 and the second sub-plate 42, defines an open insertion space 44 for insertion and mating with the sealing element 5.

[0057] Furthermore, at least a portion of the sealing element 5 is inserted between the first sub-plate 41 and the second sub-plate 42, that is, part of the sealing element 5 can extend between the first sub-plate 41 and the second sub-plate 42, and part can extend outside the first sub-plate 41 and the second sub-plate 42. The end of the heat exchange element 2 extends into the fixed bracket 4, thereby enabling the sealing element 5 to seal between the fixed bracket 4 and the heat exchange element 2, and also to seal between the fixed bracket 4 and the water tank shell 1, ensuring the sealing effect. Moreover, the first sub-plate 41, the second sub-plate 42 and the connecting plate 43 can support the sealing element 5, ensuring the reliability of the sealing element 5 in use.

[0058] In some embodiments, the first subplate 41 has a first through hole 411, the second subplate 42 has a second through hole 421, the sealing member 5 has a sealing hole 51, and the heat exchange member 2 is adapted to pass through the first through hole 411, the sealing hole 51 and the second through hole 421 in sequence.

[0059] Specifically, the fixing bracket 4 is provided with a first sub-plate 41 and a second sub-plate 42 spaced apart, and the sealing element 5 can be at least partially disposed between the first sub-plate 41 and the second sub-plate 42, and as shown... Figure 2 As shown, the first sub-plate 41 is provided with a first through hole 411, the second sub-plate 42 is provided with a second through hole 421, the heat exchanger 2 is provided with a sealing hole 51, and the heat exchanger 2 is installed in the heat exchange chamber 14 through the fixing assembly 3. The heat exchanger 2 can be sequentially inserted through the first through hole 411, the sealing hole 51 and the second through hole 421 to be connected to the fixing assembly 3. That is, the heat exchanger 2 can be sequentially inserted through the first sub-plate 41, the sealing member 5 and the second sub-plate 42.

[0060] Furthermore, the shapes of the first through hole 411, the sealing hole 51, and the second through hole 421 match the shape of the heat exchanger 2. That is, when the heat exchanger 2 is set as a circular tube structure, the first through hole 411, the sealing hole 51, and the second through hole 421 can all be constructed as circular holes. When the heat exchanger 2 is set as a flat tube structure, the first through hole 411, the sealing hole 51, and the second through hole 421 can all be constructed as oval holes. The design is highly flexible. When the heat exchanger 2 is installed on the fixing assembly 3, the outer peripheral wall of the heat exchanger 2 can fit against the inner peripheral wall of the first through hole 411 and the inner peripheral wall of the second through hole 421. This allows the first through hole 411 and the second through hole 421 to limit the heat exchanger 2 in the circumferential direction. The sealing member 5 can also seal between the fixing bracket 4 and the heat exchanger 2, ensuring the reliability of the installation and use of the heat exchanger 2.

[0061] In some embodiments, the sealing member 5 is provided with a first insertion limiting part 52, and the insertion space 44 is provided with a second insertion limiting part 441. The first insertion limiting part 52 and the second insertion limiting part 441 are inserted and fitted together and are limited in a direction intersecting with the insertion direction of the sealing member 5.

[0062] Specifically, the fixed bracket 4 is provided with an insertion space 44, and the sealing element 5 is inserted and mated with the fixed bracket 4, and as shown... Figure 2 As shown, the sealing member 5 is provided with a first insertion limiting part 52, which can be configured as an insertion groove, etc., and a second insertion limiting part 441 is provided in the insertion space 44, which can be configured as an insertion plate, etc. The first insertion limiting part 52 and the second insertion limiting part 441 are inserted and fitted together and are limited and fitted in a direction intersecting with the insertion direction of the sealing member 5. That is, the insertion groove forms an insertion interface, and the insertion plate can extend into the insertion groove through the insertion interface to be inserted and fitted with the insertion groove. The insertion plate is provided in the insertion space 44. That is, when the sealing member 5 is inserted into the insertion space 44, the fixing bracket 4 can be limited and fitted with the sealing member 5 in a direction intersecting with the insertion direction, thereby limiting the displacement of the sealing member 5 and ensuring the sealing effect of the sealing member 5.

[0063] Furthermore, such as Figure 2 As shown, in this embodiment, there are two first insertion limiting parts 52, which are spaced apart and distributed on both sides of the sealing member 5. There are also two second insertion limiting parts 441, which are spaced apart and distributed in the insertion space 44. The two first insertion limiting parts 52 and the two second insertion limiting parts 441 are arranged in a one-to-one correspondence, so that both sides of the sealing member 5 can be inserted and cooperate with the fixed bracket 4, ensuring the reliability of the insertion and cooperation, and limiting the sealing member 5 at various points, ensuring the reliability of the installation of the sealing member 5.

[0064] In some embodiments, the inner peripheral wall of the seal 5 is provided with an inwardly protruding first sealing protrusion 53, which elastically presses against the heat exchanger 2.

[0065] Specifically, the fixing assembly 3 is provided with a seal 5 and a fixing bracket 4, at least a portion of the seal 5 is placed inside the fixing bracket 4, and the heat exchanger 2 can be sequentially inserted through the fixing bracket 4 and the seal 5, such as... Figures 2-3 as well as Figure 5 As shown, the sealing element 5 is provided with a sealing hole 51, and the inner peripheral wall of the sealing element 5 is provided with a first sealing protrusion 53, that is, the sealing hole 51 is provided with a first sealing protrusion 53. The heat exchange element 2 passes through the sealing hole 51, so that the first sealing protrusion 53 can elastically press against the heat exchange element 2, thereby sealing the space between the fixed bracket 4 and the sealing element 5.

[0066] Furthermore, the first sealing protrusion 53 is configured as an annular protrusion, that is, the first sealing protrusion 53 is arranged around the heat exchanger 2, thereby ensuring the sealing effect on all parts of the heat exchanger 2 in the circumferential direction. The first sealing protrusion 53 is configured as a triangular rib structure, that is, the end of the first sealing protrusion 53 near the heat exchanger 2 is smaller in size and gradually increases in size along the direction away from the heat exchanger 2. This means that after the first sealing protrusion 53 is pressed against the heat exchanger 2, as the extrusion pressure increases, the contact area between the first sealing protrusion 53 and the heat exchanger 2 also gradually increases, thereby improving the sealing effect.

[0067] In other embodiments, the outer peripheral wall of the seal 5 is provided with an outwardly protruding second sealing protrusion 54, which elastically presses against the inner wall of the water tank housing 1.

[0068] Specifically, the fixing assembly 3 is provided with a sealing element 5 and a fixing bracket 4. At least a portion of the sealing element 5 is placed within the fixing bracket 4, and the heat exchange element 2 can be installed in the heat exchange chamber 14 through the fixing bracket 4, such as... Figures 2-3 as well as Figure 5 As shown, the sealing element 5 is partially disposed inside the fixed bracket 4 and partially exposed outside the fixed bracket 4. The outer peripheral wall of the sealing element 5 is provided with a second sealing protrusion 54. When the heat exchange element 2 is installed in the heat exchange cavity 14 through the fixing assembly 3, the outer peripheral wall of the sealing element 5 can contact the inner wall of the water tank shell 1, thereby allowing the second sealing protrusion 54 to elastically press against the inner wall of the water tank shell 1, thereby sealing the space between the fixed bracket 4 and the water tank shell 1.

[0069] Furthermore, the second sealing protrusion 54 is configured as a strip-shaped protrusion, and the second sealing protrusion 54 can be extended along the circumference of the sealing member 5, thereby ensuring the sealing effect at all points where the fixed bracket 4 and the water tank shell 1 come into contact. The second sealing protrusion 54 is configured as a triangular rib structure, that is, the end of the second sealing protrusion 54 near the water tank shell 1 is smaller in size, and gradually increases in size in the direction away from the water tank shell 1. This means that after the second sealing protrusion 54 is pressed against the water tank shell 1, as the extrusion pressure increases, the contact area with the water tank shell 1 also gradually increases, thereby improving the sealing effect.

[0070] In some embodiments, there are multiple first sealing protrusions 53, which are spaced apart along the extension direction of the heat exchanger 2.

[0071] Specifically, a first sealing protrusion 53 is provided inside the sealing hole 51 of the sealing element 5. The first sealing protrusion 53 can improve the sealing effect between the fixed bracket 4 and the heat exchange element 2, and multiple first sealing protrusions 53 can be provided, that is, two, three or four first sealing protrusions 53, etc. In this embodiment, for example... Figure 2As shown, there are two first sealing protrusions 53, and multiple first sealing protrusions 53 are distributed at intervals along the extension direction of the heat exchanger 2, so that the sealing member 5 can seal the heat exchanger 2 and the fixed bracket 4 multiple times along the extension direction of the heat exchanger 2, thereby ensuring the sealing effect of the sealing member 5 between the fixed bracket 4 and the heat exchanger 2.

[0072] In other embodiments, there are multiple second sealing protrusions 54, which are spaced apart along the extension direction of the heat exchanger 2.

[0073] Specifically, the outer peripheral wall of the sealing element 5 is provided with a second sealing protrusion 54. The second sealing protrusion 54 can improve the sealing effect between the fixing bracket 4 and the water tank shell 1, and multiple second sealing protrusions 54 can be provided, that is, two, three or four second sealing protrusions 54, etc. In this embodiment, for example... Figure 2 As shown, there are two second sealing protrusions 54. Multiple second sealing protrusions 54 are spaced apart along the extension direction of the heat exchanger 2, so that the sealing member 5 can seal the fixed bracket 4 and the water tank shell 1 multiple times along the extension direction of the heat exchanger 2, thereby ensuring the sealing effect of the sealing member 5 between the fixed bracket 4 and the water tank shell 1, so as to ensure the sealing between the heat exchange chamber 14 and the water storage chamber 17.

[0074] In some embodiments, a sealing groove 13 is also formed inside the water tank shell 1. The sealing groove 13 is located between the end of the heat exchange chamber 14 and the water storage chamber 17. The fixing component 3 is located inside the sealing groove 13, and the sealing element 5 is sealed and pressed against the inner wall of the sealing groove 13.

[0075] Specifically, the heat exchanger 2 is installed inside the heat exchange chamber 14 via the fixing assembly 3, and as follows: Figure 6 As shown, a sealing groove 13 is also formed inside the water tank shell 1. The sealing groove 13 is located between the end of the heat exchange chamber 14 and the water storage chamber 17. The fixing component 3 can be set inside the sealing groove 13. A sealing element 5 is provided inside the fixing component 3. The fixing component 3 is set between the water storage chamber 17 and the heat exchange chamber 14 so that the sealing element 5 can seal the water storage chamber 17 and the heat exchange chamber 14, thereby preventing the water storage chamber 17 and the heat exchange chamber 14 from communicating. This ensures the airtightness between the water storage chamber 17 and the heat exchange chamber 14 and prevents the first medium in the water storage chamber 17 and the second medium in the heat exchange chamber 14 from mixing, which would affect the user experience.

[0076] Thus, the heat exchanger 2 is disposed in the heat exchange chamber 14, passes through the fixing component 3, and its end can communicate with the water storage chamber 17, so that the first medium in the water storage chamber 17 can flow through the heat exchanger 2, and the second medium flows in the heat exchange chamber 14, so that when the first medium flows into the heat exchanger 2, it can exchange heat with the second medium through the heat exchanger 2, so as to transfer and store the heat in the second medium.

[0077] Furthermore, the sealing element 5 of the fixing component 3 is sealed and pressed against the inner wall of the sealing groove 13, thereby allowing the water storage chamber 17 and the heat exchange chamber 14 to be completely separated by the fixing component 3, so that the first medium can only flow through the heat exchange element 2 and the second medium can only flow through the heat exchange chamber 14, avoiding the mixing of the first and second media, improving the user experience, and the fixing bracket 4 can also support the heat exchange element 2, ensuring the installation reliability of the heat exchange element 2 and reducing the installation cost.

[0078] In some embodiments, the sealing groove 13 is provided with a first snap-fit ​​portion 131, and the fixing bracket 4 is provided with a second snap-fit ​​portion 45. The first snap-fit ​​portion 131 is adapted to snap-fit ​​with the second snap-fit ​​portion 45.

[0079] Specifically, the water tank shell 1 is provided with a sealing groove 13, which is open to one side, so that the fixing component 3 can be inserted into the sealing groove 13. This allows the sealing groove 13 to limit the fixing component 3 and ensure the installation reliability of the fixing component 3. The peripheral wall of the sealing groove 13 is provided with a first snap-fit ​​part 131, which can be configured as a snap-fit ​​groove or a snap-fit ​​hole, etc. The fixing bracket 4 is provided with a second snap-fit ​​part 45, which can be configured as a snap-fit ​​protrusion, etc. When the fixing component 3 is inserted into the sealing groove 13, the first snap-fit ​​part 131 can engage with the second snap-fit ​​part 45, thereby fixing the fixing component 3 relative to the sealing groove 13. This ensures the installation reliability of the fixing component 3, and the structure is simple and the installation cost is low.

[0080] Furthermore, in actual implementation, the first latching portion 131 can be configured in multiple ways, such as two, three, or four. In this embodiment, for example... Figure 6 As shown, the first snap-fit ​​portion 131 is configured as two snap-fit ​​holes, and the second snap-fit ​​portion 45 can also be configured as multiple, that is, the second snap-fit ​​portion 45 can be two, three, or four, etc. In this embodiment, for example... Figures 2-3 As shown, the second snap-fit ​​part 45 is configured as a snap-fit ​​protrusion and there are two of them. Multiple first snap-fit ​​parts 131 and multiple second snap-fit ​​parts 45 cooperate one by one, so that multiple parts of the fixed bracket 4 can be snap-fitted with the sealing groove 13 to improve the connection reliability.

[0081] In some embodiments, the water tank housing 1 includes a main housing 11 and a cover plate 12, the cover plate 12 being connected to the main housing 11 to jointly define a water storage chamber 17 and a heat exchange chamber 14.

[0082] Specifically, the water tank shell 1 is located on the outermost side of the water tank assembly 100, and can provide overall support for the water tank assembly 100, and as... Figure 8As shown, the water tank shell 1 is provided with a main shell 11 and a cover plate 12. The main shell 11 and the cover plate 12 can be connected by welding or other means, thereby defining the water storage chamber 17 and the heat exchange chamber 14. The cover plate 12 and the main shell 11 can be made by integral molding, which can reduce the installation cost and improve the production efficiency.

[0083] In this way, both the heat exchange chamber 14 and the water storage chamber 17 are defined by the cover plate 12 and the main shell 11, so that the heat exchange chamber 14 and the water storage chamber 17 can be connected only at the sealing groove 13. When the fixing component 3 is placed in the sealing groove 13, the sealing component 5 can seal the sealing groove 13, thereby separating the heat exchange chamber 14 and the water storage chamber 17. This can reduce the number of structures in the water tank assembly 100 and improve the lightweight design of the water tank assembly 100.

[0084] Meanwhile, the sealing groove 13 can be provided in the main housing 11 and open towards the cover plate 12. When the fixing component 3 is inserted into the sealing groove 13 and the cover plate 12 is connected to the main housing 11, the cover plate 12 can apply a pressing force towards the main housing 11 to the fixing component 3, thereby causing the second sealing protrusion 54 of the sealing element 5 to elastically press against the sealing groove 13 and the fixing bracket 4, thereby improving the sealing performance.

[0085] In some embodiments, the main housing 11 and the cover plate 12 are connected by welding. The water tank housing 1 is provided with the main housing 11 and the cover plate 12, and the main housing 11 and the cover plate 12 can be connected by welding, which simplifies the process, reduces the cost of the connection method, saves manufacturing materials, and improves the lightweight design of the water tank assembly 100. At the same time, the welded joint has good mechanical properties and sealing performance, which can ensure the reliability of the connection and the sealing performance between the main housing 11 and the cover plate 12, thereby ensuring the sealing performance between the water storage chamber 17 and the heat exchange chamber 14, and ensuring the sealing performance between the water storage chamber 17 and the outside world, thus ensuring the reliability of the water tank assembly 100.

[0086] In other embodiments, the fixed bracket 4 and the cover plate 12 are connected by welding. After the fixed component 3 is inserted into the sealing groove 13, the cover plate 12 can be connected to the main shell 11 by welding or other means. The cover plate 12 can also be connected to the fixed bracket 4 by welding. This simplifies the process, reduces the cost of the connection method, and saves manufacturing materials by welding, thus improving the lightweight design of the water tank assembly 100. At the same time, the welded joint has good mechanical properties and sealing performance, which can ensure the reliability of the connection and the sealing performance between the fixed bracket 4 and the cover plate 12. This, in turn, can ensure the sealing performance between the water storage chamber 17 and the heat exchange chamber 14, thus ensuring the reliability of the water tank assembly 100 in use.

[0087] In other embodiments, welding overflow 6 is provided at the connection between the main housing 11, the cover plate 12 and the fixing component 3. The fixing component 3 can be inserted into the sealing groove 13, and the main housing 11 can be connected to the cover plate 12 by welding. The fixing bracket 4 can be connected to the cover plate 12 by welding, so that the main housing 11, the cover plate 12 and the fixing component 3 have a common connection. In actual installation, welding overflow 6 can be provided at the connection, that is, the main housing 11 and the cover plate 12 and the fixing bracket 4 and the cover plate 12 are all completely welded, thereby ensuring the connection strength.

[0088] In some embodiments, the heat exchanger 2 is distributed in multiple groups, and the multiple groups of heat exchanger 2 are arranged sequentially along the width direction of the heat exchange cavity 14, with adjacent groups of heat exchanger 2 separated by a partition 16.

[0089] Specifically, multiple heat exchangers 2 are configured, and both ends of the multiple heat exchangers 2 can be installed on the water tank shell 1 by fixing components 3, so that the first medium in the water storage cavity 17 can flow through the multiple heat exchangers 2 respectively, so as to exchange heat with the second medium in the heat exchange cavity 14 through the multiple heat exchangers 2 respectively, thereby improving the heat exchange efficiency and ensuring the heat exchange effect.

[0090] Furthermore, multiple heat exchangers 2 are fixed at one end to the same fixing component 3, which constitutes a group. Multiple heat exchangers 2 can be set up, and multiple groups of heat exchangers 2 can be arranged along one side of the width direction of the heat exchange cavity 14. In this way, multiple heat exchangers 2 can be installed in the heat exchange cavity 14 through multiple fixing components 3, which can ensure the installation reliability of each heat exchanger 2. Adjacent groups of heat exchangers 2 can be separated by partitions 16, so that the second medium flowing into the heat exchange cavity 14 can be diverted through partitions 16, so that each heat exchanger 2 can perform heat exchange, improve heat exchange efficiency, and ensure heat exchange reliability.

[0091] In some embodiments, the water tank shell 1 is further provided with two water inlet and outlet areas 15, which are located at both ends of the heat exchanger 2, and the heat exchange channel 21 is connected to the water storage chamber 17 through the water inlet and outlet areas 15. One of the two water inlet and outlet areas 15 is provided with a first inlet 151 and the other is provided with a first outlet 152.

[0092] Specifically, the water tank assembly 100 is provided with a water storage cavity 17, which can be used to store the first medium. The water tank shell 1 is also provided with inlet and outlet water areas 15. There are two inlet and outlet water areas 15, which are located at both ends of the heat exchanger 2. Both ends of the heat exchanger 2 are connected to the two inlet and outlet water areas 15. The two inlet and outlet water areas 15 can also be connected to the water storage cavity 17. That is, the heat exchange channel 21 is connected to the water storage cavity 17 through the inlet and outlet water areas 15, so that the first medium in the water storage cavity 17 can flow to one of the two inlet and outlet water areas 15, and then flow into the heat exchanger 2, so that it can flow to the other of the two inlet and outlet water areas 15 through the heat exchanger 2, and then flow back into the water storage cavity 17.

[0093] Furthermore, one of the two inlet and outlet water areas 15 is provided with a first inlet 151 and the other is provided with a first outlet 152. The first medium in the water storage chamber 17 can flow through the first inlet 151 to one of the two inlet and outlet water areas 15, and the first medium in the other of the two inlet and outlet water areas 15 can flow back into the water storage chamber 17 through the first outlet 152, so as to form a return water flow path for the first medium.

[0094] In addition, the heat exchange cavity 14 is also provided with a second inlet 141 and a second outlet 142 at both ends along the extension direction of the heat exchange element 2. The second medium can flow into the heat exchange cavity 14 through the second inlet 141 and then flow out of the heat exchange cavity 14 through the second outlet 142 to form a return water flow path for the second medium. The structure is simple. The first inlet 151 and the first outlet 152 are distributed at intervals along the extension direction of the heat exchange element 2. The second inlet 141 and the second outlet 142 are also distributed at intervals along the extension direction of the heat exchange element 2, which can reduce the energy loss when the first medium and the second medium flow, thereby reducing energy consumption.

[0095] This utility model also proposes a washing device.

[0096] The washing device according to the present invention includes: a washing tank and a water tank assembly 100 of any one of the above, the water tank assembly 100 being adapted to supply water into the washing tank, and the water outlet of the washing tank being connected to the heat exchange chamber 14.

[0097] Specifically, the washing equipment can be configured as a dishwasher, etc., and the washing equipment is equipped with a washing tank, which forms a washing space. Users can place items to be cleaned in the washing space, and a washing spray arm is provided in the washing space. The water tank assembly 100 can be used to supply water to the washing spray arm in the washing tank, and a drain valve is provided between the water tank assembly 100 and the washing tank. When the drain valve is opened, a first medium mixed with cleaning liquid and the like can be sprayed out from the washing spray arm to clean the items, thereby improving the automation of cleaning.

[0098] Furthermore, the washing tank is equipped with a water outlet, through which the second medium, after cleaning the items, can be discharged. The water outlet is connected to the heat exchange chamber 14 via a heat exchange pipe, allowing the second medium to flow into the heat exchange chamber 14 and exchange heat with the first medium in the heat exchange element 2. This achieves waste heat recovery, improves the energy efficiency of the washing equipment, and enhances the user experience. The second medium is the medium obtained after the first medium has been heated and used to clean the items.

[0099] According to the washing device of this utility model embodiment, the sealing member 5 seals and presses against the outer peripheral wall of the heat exchange member 2 and the inner wall of the water tank shell 1 respectively, which can improve the sealing performance between the heat exchange chamber 14 and the water storage chamber 17, and improve the fixation stability and reliability of the heat exchange member 2 in the water tank shell 1. The sealing member 5 is also used to divide the heat exchange chamber 14 and the water storage chamber 17, so that the sealing member 5 is constructed as a reusable structure, which can simplify the structure inside the water tank shell 1, improve the compactness of the internal structure of the water tank shell 1, realize the miniaturization and compact design of the water tank assembly 100, and reduce the installation cost of the water tank assembly 100. At the same time, it can prevent the heat exchange chamber 14 and the water storage chamber 17 from communicating, improve the working stability and reliability, and ensure the washing effect, improve the user experience, and have a better effect and wider applicability.
